In my code below, I am having a problem saving the matrix A properly to a file. The saved data is getting mixed up and does not correspond to the matrix A. Can you help me save the data properly?
a = (0.5)*rand(20,1);
b = (0.5)*rand(20,1);
c = (0.5)*rand(20,1);
d = (0.5)*rand(20,1);
e = (0.5)*rand(20,1);
A = [a b c d e];
fileID = fopen('check.txt','w');
fprintf(fileID,'%6s %6s %6s %6s %6s\r\n','a','b', 'c', 'd', 'e');
fprintf(fileID,'%6.5f %6.5f %6.5f %6.5f %6.5f\r\n',A);

Transpose ‘A’ and it should work:
fprintf(fileID,'%6.5f %6.5f %6.5f %6.5f %6.5f\r\n',A.');
or if ‘A’ will always be real:
fprintf(fileID,'%6.5f %6.5f %6.5f %6.5f %6.5f\r\n',A');
